Washington Homestead Exemption Calculator 2025
A homestead exemption lowers the property tax on your primary residence. Washington’s median effective property-tax rate is 0.81% of home value — on the Washington median home ($562,500) that is about $4,556 a year (WalletHub ‘Property Taxes by State in 2026’ (U.S. Census Bureau ACS, collected 2026-01-29)).
Important — eligibility: Washington has no general homestead property-tax exemption; its senior/disabled exemption and deferral are income- and age-gated. So the calculator below shows the full estimated bill (no general exemption applied); enter your value to see your number, and check whether you qualify for the age/disability program.
Enter your home value below. The estimate uses the Washington median effective rate, so it is a starting point — your actual bill depends on your county’s millage and assessment. Senior, veteran and disability relief is additional. Everything runs in your browser; no value or personal data is transmitted.
Verify with the authority: confirm the current homestead rules and your local rate with the Washington Department of Revenue.
